I got my first of these cameras a few months ago. The camera and picture quality were pretty much what I expected and served my purpose well as a backup camera on the back of my caravan. During our last trip with a trailer, I noticed that the green color has turned pink. Obviously something happened to the green sensor. Since the camera was still under warranty, I contacted LASTBUS and asked for a replacement camera to be sent. The owner of LASTBUS was very responsive and did everything to ensure I was a happy customer. Communication between us was handled promptly. The replacement camera arrived within a few weeks. One nice thing about the replaceable chamber was that it included a rubber boot (as seen in my photo) that helped seal the 4-pin connection from water ingress. Honestly, I don't agree with the negative reviews about the lack of responsiveness from this seller. It wasn't my experience at all.
